The highest design temperature of API standard 650 self-anchored flat-bottom steel tanks
Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API standard 650 self-anchored flat-bottom steel tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.
The increased uplift described in API Standard 620 tank Appendix Q is intended to apply to the size of the ringwall and foundation but not the anchorage. For tanks with an internal design pressure of 1 lbf/in.2 gauge and over, the uplift, if any, shall be calculated under the combined conditions of 1.25 times the internal design condition plus the design wind load on the API standard 650 self-anchored flat-bottom steel tanks shell and roof.
X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as API standard 650 self-anchored flat-bottom steel tanks. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of API standard 650 self-anchored flat-bottom steel tanks etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
